like it says on the top right of my messages - the middle east.
there are gardening shops, but perlite, peatmoss or even coco\perlite is rarely available there. they usually are part of a nursery and don't have much variety as it comes to HOW to raise the plants.
People just buy pre-mixed bags and pots and plant their plants. Its rare that people "engineer" their mix.
Specialty shops that sells fertilizers and so on are usually expensive for the private customer. All they have is the local chemical fertilizers and plumbing parts. sometimes pots, pre-mixed soil and fake grass and the likes.
